I've just switched to telerik and are replacing my elements.

My problem is that the normal expander works and the telerik doesnt.. I've placed them next to each other in the code, to validate this.

    
            <Expander IsExpanded="{Binding Path=IsExpanded}"></Expander> 
        
            <Telerik:RadExpander IsExpanded="{Binding Path=IsExpanded}" ></Telerik:RadExpander>

Bound to

    
            private bool _isExpanded = true;  
        
            public bool IsExpanded  
        
            {  
        
               get { return _isExpanded; }  
        
               set 
        
               {  
        
                   _isExpanded = value;  
        
                   //Some code  
        
               }  
        
            }

Is this the wrong way to do it?

RadDiagram Layout() & AutoFit() - when is the proper moment to use it?

I'm adding shapes and connections manually in code behind to my RadDiagram. I'd like RadDiagram to layout shapes and fit it after adding last item, so i call RadDiagram.Layout(); and RadDiagram.AutoFit(); but that does not work. Why?

private void Button_Click_1(object sender, RoutedEventArgs e)

{

var shapes = new List<RadDiagramShape>();

for (int i = 0; i <= 15; i++)

{

var shape = new RadDiagramShape();

shapes.Add(shape);

if (i == 0)

{

_mainShape = shapes[0];

}

if (i > 0)

{

var conn = new RadDiagramConnection {Source = _mainShape, Target = shape, SourceCapType = CapType.Arrow1};

RadDiagram.Items.Add(conn);

}

RadDiagram.Items.AddRange(shapes);

RadDiagram.Layout();

RadDiagram.AutoFit();

}

Insert space issue

Hi,
I'm using the newly released version (2013.3.1016.40) of RadMaskedTextInput control.
The control has a strange behavior when inserting space.

<telerik:RadMaskedTextInput Culture="" Mask="" MinWidth="300" Margin="10,10,10,10"

HorizontalContentAlignment="Right"

UpdateValueEvent="LostFocus" TextMode="PlainText" InputBehavior="Insert" />

1. Type 1234567.
2. Put the cursor between 1 and 2.
3. Type space.
The input becomes "12 34567".

My environment: VS 2010, Windows 7.

Regards,
Gong

Get DoubleClicked Cell and its Data Coordinates

Hi all,
Is there a way to get the clicked cell (double click) with 2013-3 version?
In the previous versions and internal builds (since one or two month ago) I was able to get clicked cell with this code:

private void pivot_MouseDown(object sender, MouseButtonEventArgs e)

{

if (e.ClickCount == 2)

{

RadPivotGrid p = sender as RadPivotGrid;

FrameworkElement cell = e.OriginalSource as FrameworkElement;

then with cell object I was able to read properties such MDX coordinates to open for example a drill down data window.

Now if I try this code the cell variable is null. How can I get clicked cell and then MDX coordinates? Is it possible?

Many thanks in advance!

Best Regards,
Davide

RadRibbonWindow Title Bar Issue with Win8 and VS2012RC

Hi,

I'm using Telerik RadControls for WPF Q2 2012 within Visual Studio 2012 RC. Generally, I've no problems, except with the RadRibbonWindow, which displays a light blue bar over the entire Title Bar area, effectively covering up the three buttons on the upper right hand side (see attached image). The problem appears to be similar to that found in the post "trying to run existing application with RadRibbonWindow in Win8... Aero2 error" within this same forum.

In that post (dated 07/12/2012), Viktor (from Telerik) replies that an internal build will be available in a week (approx. 07/19/2012). However, I find no internal build that addresses this issue. To be specific, my version of Telerik.Windows.Controls.RibbonView is 2012.2.607.40 and the runtime version is v4.0.30319.

I'm replacing the standard WPF MainWindow XAML file Window control with a Telerik RadRibbonWindow and set "RadRibbonWindow.IsWindowsThemeEnabled = false;" in the static constructor of MainWindow. I'd appreciate any direction or fix you can provide.

Thanks,

Chris A

GridViewDataColumn and two way binding

Hi,

I have a gridview, where one of the columns are defined like this:

Two questions:

1)

<telerik:GridViewDataColumn DataMemberBinding="{Binding ApprovedForRI, Mode=TwoWay}"
Header="ApprovedForRI" Width="Auto" IsReadOnly="False"/>

and it is bound to an object, with property like this:

public override bool ApprovedForRI
{
get
{
return base.ApprovedForRI;
}
set
{
base.ApprovedForRI = value;
OnPropertyChanged("ApprovedForRI");
}
}

What I am trying to do is when I check/uncheck the box on UI in ApprovedForRI column, the "set" should get called, so the PropertyChanged event is fired, but I don't see this happening. What is the right way to achieve this.

2)
It seems like to check/uncheck the box, I need three clicks. first to select the cell, 2nd to select the checkbox, and finally 3rd to check/uncheck. Is there any way to make it single click, once row is selected?

Thanks.

Scrolling uisng arrow keys

Hi,

The PDFViewer does not scroll correctly using up/down arrow keys, sometimes it does nothing and sometimes it jumps. Is scrolling supported uisng arrow keys? Is there any API available to scroll line by line like jumping to specific page or page up/down?

Thanks

HierarchyChildTemplate Header Binding Issuse

Hi,

I am using a HierarchyChildTemplate in which I have bound the Header to our language file attempting to extract the correct header for the column.

In the case of a standard RadGridView the implementation works perfectly fine and I get the column header in the desired language

In the case of the HierarchyChildTemplate using the exact same solution results in the Column Header displaying the Path variable name of the bound DataMemberBinding instead?

I have tried a number of different binding solutions for the header however is seems Binding does not work.

Has anyone else experienced the same issues? or have a working example?
